Embodiment Construction

[0017] The purpose and effect of the present invention will become more obvious by describing the present invention in detail according to the accompanying drawings and specific embodiments. The present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0018] Such as figure 1 Shown is a logical deployment diagram of the blockchain-based trusted data grid system of the present invention, and the blockchain-based trusted data grid system needs to be deployed together with the blockchain. The blockchain part is responsible for the authority control of the trusted data grid system, data element information management, data transaction settlement, access record management, etc. The trusted data grid system network is composed of multiple trusted data grid system n...

Abstract

The invention discloses a trusted data grid system based on a block chain. The trusted data grid system provides services of off-chain trusted data storage, exchange and calculation in combination with the block chain. Services of the trusted data grid system include a software development package, a data island, a data agent and the external block chain. The software development package providesan interface for a software developer to use the trusted data grid system; the data island provides related services of single-node data storage, calculation, network management and the like; the dataagent service provides a method for anchoring off-chain data and on-chain data meta-information; and the external block chain is mainly used for providing authority control, data authority confirmation, data transaction and other services of the trusted data grid system. The invention provides a brand-new off-chain data trusted management scheme, so that the problem that an existing block chain is insufficient in big data storage and exchange performance is solved.

Description

technical field [0001] The invention relates to blockchain technology and trusted data management technology, in particular to a trusted data grid system based on blockchain. Background technique [0002] Blockchain technology, blockchain is a new type of decentralized protocol that can safely store digital currency transactions or other data, information cannot be forged and tampered with, and transaction confirmation on the blockchain is shared by all nodes on the blockchain Finish. Due to its consensus algorithm, encryption algorithm and other mechanisms, the blockchain can effectively manage data asset data, such as copyright data, contract data, game props, etc. A smart contract is an automatically executable program deployed on the blockchain. A smart contract in a broad sense includes programming languages, compilers, virtual machines, events, state machines, fault-tolerant mechanisms, etc. Smart contracts combined with blockchain can effectively perform services su...
